PUNCHING-BAG EXERCISER.

SPECIFICATION forming part of Letters Patent No. 663,690, dated December 11, 1900. Application filed February 19, 1900- Serial No. 5,681. (No model.)

To all whmn it may concern.-

Be it known that We,ALEXANDER A. WHITE- LY,a resident of the city of New York,borough of Manhattan, New York county, and WIL- LIAM A. DUNCAN, a residentof New York, (Long Island City,) Queens county, State of New York, citizens of the United States, have invented certain new and useful Improvements in Punching-Bag Exercisers, of which the following is a specification.

Our invention relates to punching-bag exercisers, and has for its object to provide a simple and efficient means of attaching 0r securing a punching-bag to a standard and so that the bag maybe readily attached to and detached from such standard.

To this end the invention consists in the novel details of improvement and the combination of parts hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part hereof, in which Figurel is a longitudinal cross-section of the punching-bag and head portion of the standard on the line 3 3 of Fig.2. Fig. 2 is a sectional view of the bag fastened over the head of the standard, the section being taken on the line 4: 4 of Fig. l; and Fig. 3 is a detail view, partly in cross-section, of the standard and its head.

In the drawings, A indicates the standard, at one end of which is a head or top piece G, whose base is slightly concave and whose other side is of cofivex or rounded shape, as shown; but the shape of the head G may be varied, if desired.

H indicates the usual bladder or inner portion of a punching-bag and is adapted to be inflated through the medium of the valvestem B indicates the outer or enveloping covering of the inner bag H. This envelopingcover B is preferably made of leather and is open or slitted atj for a portion of its circumference, so as to permit of the insertion of the head G of the standard, the edges of the slitted portion of the outer bag or coveringB being adapted to be laced over or around the head G by lacing it; but other means may be employed for drawing together the edges of the slit portion of the outer bag B over the head G. In the head G we provide an opening or aperture Z, through which the valve- Stem '1; of the inflatable bag may be passed.

To attach the bag to the standard, the head G is inserted through the opening or slitjof the outer bag B and the valve-stem t' of the inner bag H inserted through the aperture Z in the head G. The edges of the opening in the enveloping cover B are thereupon laced together or otherwise fastened over the head. As the inner bag or bladder H is inflated and expanded it will press against the base of the head G and expand with it the outer bag or covering B, and the greater the expansion the more firmly will the outer bag B press upon and grasp the head portion G of the standard, the inner bag H at the same time also bearing with greater pressure upon the face of the head G, and thus the outer covering B is offectively held over and around the head G. In this manner we produce a simple and efficient means of attaching the bag to the standard, at the same time permitting the bag to be readily detached therefrom.

We do not limit the invention to the precise details shown and described, as they may be varied Without departing from the spirit of our invention.

NVhat we claim, and desire to secure by Letters Patent, is

1. The combination of a standard having a head, with an inflatable bag and an enveloping covering substantially surrounding the bag and the said head, the enveloping coveringhaving an opening through which the head and bag can be passed with means for detach ably secu ring the covering over said head,

. tially surrounding the inflatable bag and the said head, with means for detachably scour: ing the edges of the opening of the enveloping covering together across the outer part of the head transversely of the latter.
